it's definitely a great work.but let's calculate : In 2017 Harry's sons are studying at 1 and 3 grade, and the Luna's children is on the 7 grade? Luna is the same age as Ginny. I don't think she got married so soon. So, I think Lorcan/Lysander should be next to Fred or to James in "Next Generation part 1" [link] or to make a series of individually for Salamander brothers. Oh, I would gladly have looked it. If you want to work with the next generation of course.

Hey Thanks for both of your comments!In "A year in the Life" JK Rowling actually revealed that Luna marries a long time after her friends - which means Lorcan & Lysander are probably a lot younger than Albus, Lily etc. But when I made this I didn't know about that... and I can still imagine her getting kids in her early 20s ;D
